REPLACING THE LENS
WARNINGS: (1) Before undertaking any work on the laser
marking system, remove the mains power plug.
(2) This procedure is to be performed by fully
trained engineers only.
(3) The lens must not come in contact with
unprotected skin (health hazard).
CAUTION: Protect the lens from damage by shock or
scratching.
The lens consists of the optics retainer and the focusing lens, which has
been adjusted at manufacture.
Notes: (1) Ensure the replacement lens is available before starting this
procedure.
(2) In addition to its primary
optical purpose, the
objective, with its built-in
lens, simultaneously acts
as protection from dust
and alike for the beam
scanning unit. As a
result, the lens should
not be removed for any
longer than necessary.
(3) To exchange the lens fit
the lens cover to the
lens. The cover is
delivered with every
system.
(4) Release these two
screws and pull out the
lens cover together with
the lens. The lens is then held by 2-O-rings and no screws.
(5) To mount a lens, plug in the lens together with the lens cover
and fasten the two screws.
